"The gymnosperms are a group of seed-bearing plants that includes conifers, cycads, Ginkgo, and Gnetales. The term "gymnosperm" comes from the Greek word gymnospermos (γυμνόσπερμος), meaning "naked seeds", after the unenclosed condition of their seeds (called ovules in their unfertilized state). Their naked condition stands in contrast to the seeds or ovules of flowering plants (angiosperms), which are enclosed during pollination. Gymnosperm seeds develop either on the surface of scale- or leaf-like appendages of cones, or at the end of short stalks (Ginkgo).
The gymnosperms and angiosperms together comprise the spermatophytes or seed plants. By far the largest group of living gymnosperms are the conifers (pines, cypresses, and relatives), followed by cycads, Gnetales (Gnetophyta, Ephedra and Welwitschia), and Ginkgo (a single living species)."
Quotation from Wikipedia What are the Spermatophytes?
Spermatophytes are plants that produce seeds. They include:
cycads, a subtropical and tropical group of plants with a large crown of compound leaves and a stout trunk,
Ginkgo, a single living species of tree,
conifers, cone-bearing trees and shrubs,
gnetophytes, woody plants in the genera Gnetum, Welwitschia, and Ephedra
angiosperms, the flowering plants, a large group including many familiar plants in a wide variety of habitats.
